Bug in loading the BLE code into the board

[Haaris]

I'm using nrf52832 and building projects on it with the help of sdk 14 and sdk 11 for BLE. Now when I load my code for example the BLE HRS it loads properly with no error but on the board, it runs the previous code which was loaded into it. But when I drag and drop a hex file which I got from "Getting started with nRD52 - DK " page -

www.nordicsemi.com/.../Getting-started-with-the-nRF52-Development-Kit

it runs properly. And then after loading this hex file into nordic board and then using keil I load my BLE HRS code then it runs properly. Is there any way of rectifying this problem

Hello Haaris. Before the DK can be programmed with a user application, it must be flashed with the correct SoftDevice. The SoftDevice is a preprogrammed hex file that contains all the necessary functions to control the radio in BLE mode. Hex for SoftDevice for your appplication you will find under SDK_PATH\components\softdevice\s132\hex.

So all I have to do is drag and drop the s132_nrf52_2.0.0_softdevice.hex into the DK ???

I think so but never used it like that. I use nrfjprog for flashing my dk.

Okay do u know the specific command for that ? Or any tutorial which might help me to use nrfjprog, because i've never used it before !

You can do something like this:

nrfjprog --family nRF52 --eraseall
nrfjprog --family nRF52 --program [SOFTDEVICE_LOCATION]\s132_nrf52_5.0.0_softdevice.hex

Then you can use Keil to flash the application code.

If you prefer, you can also use the GUI program nRF Go Studio. Can be downloaded here.
